dockerfile can't be ran

  • 772

Here's my Dockerfile:

FROM php:5.5-apache

COPY sites-enabled.tgz /root/sites-enabled.tgz

RUN cd /etc/apache2/sites-enabled && \
    tar xvf /root/sites-enabled.tgz

I have a number of sites that need to be configured and I figure the easiest way to go about configuring them is to just copy the config files for the sites into the appropriate directories. Unfortunately I'm not able to do so.

I do docker build -t mywebsite . and then docker run -d mywebsite. Both of those commands appear to run just fine. The last one gives me a hex encoded string. But then when I do docker ps I don't see any machines running.

Typically, the files in sites-enabled are symlinks to sites-available. idk if that's the case in every case but if it is then it seems like it might be necessary to copy the sites-available sites over as well. eg.

FROM php:5.5-apache

COPY sites-available.tgz /root/sites-available.tgz
COPY sites-enabled.tgz /root/sites-enabled.tgz

RUN cd /etc/apache2/sites-available && \
    tar xvf /root/sites-available.tgz

RUN cd /etc/apache2/sites-enabled && \
    tar xvf /root/sites-enabled.tgz

Unfortunately, that doesn't work either. With sites-available.tgz it does but not sites-enabled.tgz.

Any ideas?

    the container does what you say, it makes a copy on the file and puts into the container, then it goes to the directory and finally it decompress the file, and that's it. You're not declaring a CMD command which will initialize apache, or do anything, so your container will not stay up unless you do that

    try putting this at the end of the dockerfile CMD /usr/sbin/apache2ctl -D FOREGROUND

    let me know how it goes
